A monolithic integrated circuit decoder for deriving stereophonically related audio frequency signals from a composite signal includes an input circuit for generating DC voltage-balanced signals including the composite signal for balanced, linear operation of the decoder. The decoder further includes a phase-locked loop having a temperature compensated current controlled oscillator and a frequency dividing dual rank flip-flop of simplified structure producing a staircase waveform on alternate half-cycles. The decoder also includes an audio mute circuit for muting the output of the decoder between stations.
